Two lidar instruments were installed at the Sakurajima volcano at the end of November 2014. These Sakurajima lidar instruments were the first to specifically observe the eruptive products of this volcano in Japan. The Sakurajima volcano is one of the most active volcanoes in the world and is in the best location for observing eruptive products. Volcanic ash is the most fine-grain of eruptive products with the particles size of atmospheric aerosols. The lidar instruments can observe such fine volcanic ash. Small eruptions, unreported by the Japan Meteorological Agency, can be detected by the lidar instruments set up at the Sakurajima volcano.
